``But what is blight to some is proving an opportunity to remake parts of the city for others living there. The Old Redford part of Detroit has suffered its share of desolation. The police station, high school and community centre are closed. Yet the area is being revitalised, led by John George, a resident who began by boarding up an abandoned house used by drug dealers 21 years ago and who now heads the community group Blight Busters. They are pulling down housing that cannot be saved and creating community gardens with fresh vegetables free for anyone to pick.''
